gdb crashes when printing a vector before it is defined #32954
Description
When debugging something like the following with rust-gdb
fn main() {
let x: Vec<i32> = Vec::new();
}And doing something silly like the following
$ rust-gdb ./test
(gdb) br main
(gdb) frame
#0 test::main () at test.rs:2
2 let mut x: Vec<i32> = Vec::new();
(gdb) print x # printing x before it is defined
gdb freezes and will eventually be killed (on another of my machines a Python Exception is raised). This didn't occur with primitives (integer, slice, &str), but Python Exceptions were raised with Option, String, etc., but Vec was the only one that caused gdb to crash. Probably not too important since checking the values of items before they are defined is not useful.
